Regarding the steel known as Blue Steel Hyper, Keizaburo wrote a brief handwritten explanation, as shown in the last image. Below is my translation of it:

“青紙ハイパー鋼刃
「青紙スーパー」をよりキメ細かく、粘り強くした鋼になります。
上手く作ることが出来れば、「青スーパー鋼系」「東郷鋼系」、当方手持の一部の青１鋼の中で最もキメ細かく、欠け難い刃になります。
惜しむらくは、鋼の在庫が少ない事であります。”

“Aogami Hyper Steel
This steel features a finer grain structure and greater toughness than "Aogami Super."
If crafted well, it produces a blade that is the finest-grained and most resistant to chipping among the "Aogami Super steel series," the "Togo steel series," and certain batches of Aogami #1 steel that I have on hand.
Regrettably, the stock of this steel is quite limited.“

※ Regarding the chrysanthemum engraving: the chrysanthemum is a symbol of the Japanese Imperial Family, and using a specific number of petals is restricted by law.
However, the engraving on this blade features 8 petals, ensuring full regulatory compliance. The stamp manufacturer has also confirmed that there are no legal or compliance issues whatsoever with using this design.

※ Regarding the explanation of the inscription “無事是名馬” on the inside of the box cover. As the completion of the order neared 2026, which is the Year of the Horse, Keizaburo inscribed his personal motto, '無事是名馬' (Buji kore meiba), on the inside of the box lid as a blessing. The literal meaning of this phrase is: Even if a horse's natural abilities are slightly lacking, as long as it stays healthy and free from injury or illness, it is truly a fine horse. This saying teaches us that in work and sports, the most important thing is not extraordinary talent, but rather a “healthy and consistent performance.”
